Problems solved by technology

However, there are still a large number of non-water-resistant dry powder putty being used indiscriminately, resulting in peeling and pulverization of some interior walls that use dry powder putty, which brings a lot of trouble and waste to users.

Abstract

The invention discloses an interior wall putty powder, which comprises the following raw materials in parts by weight: microcrystalline cellulose 15-20, butyl acrylate 7-11, gray calcium 40-46, polyvinyl alcohol 12-16, polyvinyl chloride 5 ‑10, soluble starch 14‑20, zeolite 15‑21, heavy calcium carbonate 83‑95, accelerator 3‑6, antifungal agent 1‑4. The excellent effect of the present invention is also manifested in that the putty powder obtained in the present invention uses proper raw materials, which not only reduces the cost of the putty to a certain extent, improves its anti-cracking performance, but also reduces the water absorption of the putty and improves its water resistance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an interior wall putty powder and a preparation method thereof. Background technique [0002] Putty is a kind of base material for leveling the wall, which lays a good foundation for future decoration (painting and wallpaper). Putty is divided into two kinds: putty inside wall and putty on exterior wall. External wall putty can resist wind and sun, so it has good gelation, high strength and low environmental index. The comprehensive index of putty in the inner wall is good, and it is hygienic and environmentally friendly. Therefore, the inner wall is not for external use and the outer wall is not for internal use. The traditionally used interior wall putty is gypsum or cement based, so rough surfaces are easier to bond firmly. Interior wall putty is a surface filling material for pretreatment of the construction surface before paint construction. The main purpose is to fill th...
